Chapter 12 - Transportation
LTL (less than truckload) vs TL (truckload)
LTL: shipments range from about 150 - 10000 lbs; often too big to be handled manually, yet they do not fill an entire truck; TL: shipments greater than 10000 lbs; the weight is close to the amount that would physically fill a truck trailer
**can coal be moved through a pipeline?
YES
availability
ability of a mode to service any given pair of locations
which mode of transportation is best at speed?
air
birdyback transportation
air and truck
which mode of transportation has the highest variable cost?
air cargo transportation
which mode of transportation has the the 2nd lowest fixed cost?
air cargo transportation
why does the cost curve start above zero in the distance vs cost graph
because of fixed costs associated with pickup and delivery regardless of distance
why does the cost decrease in economy of scale
because the fixed cost of the carrier is allocated over a larger weight of shipment
agents role and perspective of participants
brokers and fright forwarders; facilitate carrier and customer matching
how can shippers reduce their risk?
by improved packing and loading (ex: dunnage); by reducing susceptibility to loss or damage
the influence of market factors on transportation costs
carriers must find a backhaul load or vehicle is returned empty; imbalances in volume between shipping points can result in higher transport costs
the influence of potential liability on transportation costs
carriers must pay for liability insurance or accept financial responsibility
the influence of weight on transportation costs
cost per pound decreases as weight increases until the carrier vehicle is full; relationship starts again for the next vehicle load
the influence of density on transportation costs
cost per unit of weight declines as product density increases; higher density products allow fixed transport costs to be spread over more weight
carriers role and perspective of participants
desire to maximize their revenue for movement while minimizing associated costs
government role and perspective of participants
desires a stable and efficient transportation environment to support economic growth
the influence of distance on transportation costs
directly contributes to variable expenses (labor, fuel, and maintenance)
speed
elapsed movement time from origin to destination
pipeline cost
highest fixed cost (right-of-way, construction, requirements for control stations, and pumping capacity); lowest variable cost (no labor cost of any significance)
restrictive element
in-transit inventory is "captive", usually inaccessible during transportation
flexible element
inventory can be diverted during shipment to a new destination
in-transit inventory
is captive in the transport system
public role and perspective of participants
is concerned with transportation accessibility, expense, and standards for security, safety, and the environment
longer distances in economy of distance increases or decreases the per mile charge?
longer distances allow fixed cost of the carrier to be spread over more miles, lowing the per mile charge
air cost
low fixed cost (aircraft and handling and cargo systems); high variable cost (fuel, labor, maintenance, etc)
truck cost
low fixed cost (highways in place and provided by public support); medium variable cost (fuel, maintenance, etc)
water cost
medium fixed cost (ships and equipment); low variable cost (capability to transport large amount of tonnage)
weight of load vs cost per pound slope
negative (decreasing)
freight forwarders
not modes, but from the shipper's viewpoint, they are analogous to other carriers; two types: surface and air
diversion
occurs when a shipment destination is changed after a product is in transit
the influence of stowability on transportation costs
odd package shapes and sizes can waste cubic capacity; items with rectangular shapes are easier to stow
shippers' association
perform basically the same function as surface and airfreight forwarders, except they do not operate as profit-making organizations (membership based)
which mode of transportation is best at dependability?
pipeline
which mode of transportation is best at frequency?
pipeline
which mode of transportation has the highest fixed cost?
pipeline transportation
which mode of transportation has the lowest variable cost?
pipeline transportation
distance vs cost slope
positive (increasing)
internet role and perspective of participants
provides a vital communication link between transactional participants as well as providing and information exchange
which mode of transportation ranks in the middle for characteristics?
rail
piggyback transportation
rail and truck; either truck trailer-on-flatcar or container-on-flatcar; to take advantage of rail's low transportation costs on the line-haul along with truck's ability to provide door-to-door service
transport lane
refers to movements between origin and destination points
economic regulation
seeking to make transportation equally accessible and economical to all without discrimination
the influence of handling on transportation costs
special equipment may be needed to load and unload trucks, railcars, or ships; how products are grouped together in boxes or pallets will also impact handling costs
trucking key benefits
speed of transit; ability to operate door-to-door; more efficient than rail for small shipments over short distances
social regulation
takes measures to protect public safety and environment
capability
the ability to handle any load size or configuration
transportation
the actual, physical movement of goods and people between two points
economy of distance
the cost per unit weight decreases as distance increases; often called the tapering principle
economy of scale
the cost per unit weight decreases as the size of the shipment increases
product movement
the movement of inventory to specified destinations
dependability
the potential variance from expected delivery schedule
frequency
the quantity of scheduled movements a mode can handle
tapering principle
the rate of cost decreases as distance increases (distance vs cost graph)
what is the goal of transportation?
to maximize the size of the load and distance shipped while still meeting service expectations
biggest cost of logistics is
transportation
which mode of transportation is best at availability?
truck
which mode of transportation is the best overall for characteristics?
truck
intermodal transportation
using a container or other equipment that can be transferred from the vehicle of one mode to the vehicle of another mode without the contents being reloaded or disturbed
which mode of transportation is best at capability ?
water
fishingback transportation
water and truck
which mode of transportation ranks between rail and truck in fixed costs?
water transportation
density
weight and volume
brokers
companies that look to match a shipper's freight with a carrier to transport it
shipper and consignee role and perspective of participants
have a common interest in moving goods from origin to destination within a given time at the lowest cost
rail costs
high fixed cost in equipment, terminals, tracks, etc; low variable cost
mode
identifies basic transportation method or form
product density vs cost per pound slope
negative (decreases)
transportation consumes
time, financial, and environmental resources
